vApplication led'un'e 13, 19'01. `Serial No. 64.363. (No model.)

.T @ZZ whom, it muy concern:

Be it known that I, JOHN R. LONG, a citizen 'of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented a certain new and useful Improvement in Vises, of which thefollowing is a specification;

My invention has relation to improvements in that class of vises used bymechanics and artisans in their work.

The object of my invention is to produce a 'new and improved viseadapted to the uses aforesaid revolubly mounted to turn on a pivotalpost and so constructed that t-he tight"- 'ening of the jaws by thescrew will lock the vise against rotation on its pivot.

To the accomplishment of the aforesaid objects my invention consists inthe peculiar and novel construction, arrangement, and combination ofparts hereinafter described and then specifically pointed outin theclaims, reference being had to 'the accompanying drawings, which form apart of this specification.

In the accompanying drawings, in which similar referencesnumeralsindicate like parts in the different views, Figure 1 is a side elevationof myimproved vise mounted on a timber support, the ends of which arebroken away; Fig. 2, a central vertical longitudinal section of thesame; Fig. 3, a horizontal section of the same at the line cox of Fig.1, and Fig. 4 a section at the line y 'y of Fig. 1.

Referring to the figures, l is a circular metallic plate and for thepurpose of illustration secured on a wood beam or table 2 by means of abolt 3. Thiscircular plate has one side bent downward at a right angle,and in its center is a hole through which is passed the securing-bolt 3.On the plate 1 and preferably integral therewith is a cylindrical upwardsleeve 4, accurately internally and externally turned. The fixed jaw 5has a cylindrical portion 6, internally bored to fit the sleeve 4, andalso has an integral arm 7 to forni a support for the movable jaw andhas an opening for the reception and movement of the' movable jawtherein. The movable jaw S is integral with a sliding bar 9, which baris in form of an inverted rectangular trough adapted to fit and slide inthe opening in the fixed jaw. Lengthwise through the sliding bar 9 ofthe movable is the actuating-screw 10, provided with the usual slid'-ing lever 11 and having a collar 12 to retain it. Revolubly seated inthe sleeve 4 is a nut 13, the lower part of which is turned to fit insaid part, and the upper portion has a transverseinternally-screw-thr'eaded openin g to re'- 'ceive th'e screw 10.

In Operation the fixed jaw is revolved hori- Zontally on the sleeve tuntil the vise is in the position desired by the operator. The object tobel operated upon is then placed beL tween the jaws and the movable jawclamped against it by revolving the screw by means of the handle 11. Theoperation just described causes the screw to draw the nut 13 toward theactuating-handle of the screw and brings the depending part of the nutagainst the sleeve 4, and thus binds the vise from rotation, while thepressure of the jaws is maintained upon the object in the vise byfrictional contact between the depending part of the nut 13 and thesleeve 4. This frictional contact is not wholly due to the clamping ofthe nut 13 against the sleeve 4, but is aided by the fact that thedrawing of the upper portion of the nut by the screw 10in one directioncauses an almost imperceptible tilting of the axial line of thecylindrical portion of the nut within the sleeve, thus causing a bindingeffect against both sides of the sleeve 1.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination in a vise of the kind designated consisting ofabase-plate provided with a raised sleeve, a fixed jaw adapted toinclose said sleeve and revolve thereon, amovable jaw provided with anintegral bar adapted to pass through said fixed jaw, a threaded shaftmounted in said movable j aw, a nut situated in said movable jaw andmeshing on said screw-threaded shaft provided with a dependingcylindrical part adapted to enter and fit in the sleeve on saidbase-plate, substantially as shown and described.

2. The combination in a vise of the kind designated of a base-plate,means to fasten said base-plate to apermanent 0b.] ect, a sleeve risingfrom said base-plate, a fixed jaw adapted to inclose and revolve on saidsleeve, a movable jaw provided with an extension to pass IOO throughsaid xed jaw, means as a screw to In testimony that I claim the aboveherecause said jaws to approach and recede from unto set my hand in thepresence of two sub- 1o one another, a. nut mounted on said screwproscribing witnesses.

vided with a dependimr portion adapted to 5 enter and t the interior: ofsaid sleeve and to JOHN R LONG' be drawn against one side thereof by theac- In presence of tion of said screw in clamping said jaws, sub- C. P.HUMPHREY,

stantially as shown and described. C. E. HUMPHREY.
